Get to y=mx+b form
m=slope
b=yint

2x-y=4
minus 2x from both sides
-y=-2x+4
times -1
y=2x-4
slope=2
yint=-4

equation of horizontal line is y=value

slope=rise/run, so rise is 0 and run is inifnity so 0 is slope

ycoordinate oof every point of a horizontal ine is the value above mentioned (value)

equation of vertical line is x=value

slope is rise/run, since run=0, it is infinity/0 which is undefined, slope=undefined

xcoordinate is equalt to the value (x=value)

general form of the equation of a line is y=mx+b or ax+by=c
every line has an equation that can be writeen in slope-intercept form

the line may not visually appear to have the slope indecated because somethimes the tick marks are not equal distance (use square viewer)

Determine the slope and y-intercept of the linear equation 2x - y = 4
2

The equation of a horizontal line is y=value. The slope of a horizontal line is 0. The y-coordinate of every point on the graph of a horizontal line is value (the one from y=value). The equation of a vertical line is x=value. The slope of a vertical line is undefined. The x-coordinate of every point on the graph or vertical line is value (x=value). The general form of the equation of a line is ax+by=c. Every line has an equation that can be written in slope-intercept form. When a graphing utility is used to sketch a straight line, the graph of the line may not visually appear to have the slope indicated by its equation because the tick marks are not equally spaced

The equation of a horizontal line is y=value. The slope of a horizontal line is 0. The y-coordinate of every point on the graph of a horizontal line is value (y=value). The equation of a vertical line is x=value. The slope of a vertical line is undefined. The x-coordinate of every point on the graph or vertical line is value (x=value).

The general form of the equation of a line isax+by=c. Every line has an equation that can be written in slope-intercept form. When a graphing utility is used to sketch a straight line, the graph of the line may not visually appear to have the slope indicated by its equation because the tick marks are not equally spaced

Answer from: Quest

y < -3

step-by-step explanation:

-3y - 2 > 7

-3y -2 + 2 > 7+2

-3y > 9

-3y/-3 < 9/-3 (change the inequality sign when multiplying or dividing by a negative number)

y < -3

Answer from: Quest

answer: c, the green line

step-by-step explanation:

there is no black line, eliminate b.

simple interest implies periodic payments, but the red line shows no payments, eliminate d.

simple interest has equal payments. if paid say every day, the graph is about a straight line (actually a stairstep).

the yellow line is not straight, eliminate a.

check: the green line is straight, answer is c.

simple interest with positive interest rate gives a straight line sloping up to the right. green line:

g(t) = $100 + ($200-$100) ÷ (20 years) × (t years)

= $100 + (4%/year) × ($100)(t years)

incidentally, the yellow line curving upward represents continuously compounded interest

y = $100 × 2^(t years / (14 assuming the yellow line hits $200 at 14 years. 2^0 is 1, so y(0) = $100; 2^(14/14) is 2, so y(14) = $200.

The graph below shows the value of a $100 deposited into three different accounts over a period of 2
