Find the equation of the line with a y-intercept of -3 and a x-intercept of -4.5

So with intercepts, we know that one of the coordinates is 0 - that is because the line intercepts the axis at this point.

When we have a y-intercept of -3, it is written as (0,-3)

And when we have an x-intercept of -4.5, we write it as (-4.5,0)

So now we have our two points - let's find the slope using the equation:

--->

If we convert -4.5 to an improper fraction, we get:

So then we go back and simplify:

So now we have our slope: . Then we can write the equation:

Let's use the point (0,-3) to solve for b:

So now we can write the equation:

This is the equation of the line with points (0,-3) and (-4.5,0).

i think the answer is seven, for if i'm being useless °ω°

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.
