Question

PLS HELP What is the slope & y-intercept of the line that passes

through the points: (-2,7) & (6,-3) ? *

a.Slope: 5/4; y-intercept: 4.5
b.slope: -4/5; y-intercept: 4.375
c.slope: -1.25; y-intercept: 4.5
d.slope -5/4; y-intercept: -4.5
e.None of these​

Answer 1

C.) slope: -1.25; y-intercept: 4.5

Explanation:

-1.25 is the same as 5/4, which is the rise/run for this equation in particular.

The following equation can be used to find the Y-intercept for this graph:

`-3 = (5)/(4) (6) + b\\-3 = -7(1)/(2) +b\\4.5=b`

Therefore, our y-intercept for this line is positive 4.5 and the slope is -1.25 or -5/4
