Question

Problem is attached in the picture.

Answer 1

So you have two points to work with...

Answer 2

for slope, y2 - y1 divided by x2 - x1. this is telling us the change in y divided by the change in x.

Answer 3

it's easier to see graphically.

Answer 4

slope = (y2-y1)/(x2-x1)
=> slope = (-3-4)/(-5-0)
= -7/-5
=7/5

Answer 5

once you find the slope, (-3-4) / (-5-0)... you can use the point slope formula...which is
y - y1 = m(x-x1) where m is (7/5)

Answer 6

use either one of the points given and put them into the point slope formula...

Answer 7

(0,4) looks easier to work with I guess so...

Answer 8

y - (4) = (7/5)(x-0)

Answer 9

y = (7/5)x + 4 to graph that, just plot the two givin points in the beginning, and draw a straight line through them since this is a linear equation.

Answer 10

y = mx + b is linear
y = mx^2 + b is not linear. the square causes a curve.
