(Due in 20 minutes!) Write an equation of the line in point-slope form that passes through the given points in the table. Then write the equation in slope-intercept form.

Step-by-step explanation:

Slope interccept form: y=mx+b

(m= the slope, b= the y-intercept (the y value when x=0))

for every 2 x-values the y-value increases by 1. Slope is written as   or   which is the change in the y-values divided by the change in x-values. You can find the slope by plugging in points.

    so now you have

b is whatever the value of y is when x=0. According to the table when x=0 then y=-40. The final equation is

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
