If a line with a slope of -2 crosses the y-axis at (0,3), what is the equation of the line? i have no idea how to work this problem

So for this, we will be putting the equation in slope-intercept form, which is , with m = slope and b = y-intercept (aka the point in which the line crosses the y-axis)

Since it's stated that -2 is our slope, this means that -2 is the m variable.

Since it's also stated that the y-intercept is (0,3), 3 is our b variable.

Putting our equation together, it's

step-by-step explanation:

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.
