Question

Write an equation of the line that passes through a pair of points: (-4, -3), (-3, 1)

a. y = 4x -13)
b. y = -4× 13)
c. y = 4x +13)
d. y = 4x -1/13​

Answer 1

C. y=4x+13

Explanation:

To solve this equation first find the slope. Do this by using the slope formula, m=
`(y_(2)-y_(1) )/(x_(2)-x_(1) )`, so plug in the points
`(1+3)/(-3+4)` which equals 4/1 or 4. Since now we know the slope is 4 we can put the equation into slope-point form, I will be using (-4,-3) for this equation. y+3=4(x+4), then solve for y. After solving you get y=4x+13.
