NEED HELP ASAP please help
Lerok [7]

Answer:

a) 7/5

your y - intercept is wrong btw, the x should always be 0 on a y-intercept so it should be (0,7)

y-7 = 7/5 (x)

Step-by-step explanation:

given the x intercept = (-5,0) and the y intercept = (0,7), we can plug these points into the slop equation

y1-y2

____ = m

x1-x2

m = (0-7)/(-5-0) = -7/-5 = 7/5

slop-intercept form is basically point slope form

y-y1 = m(x-x1)

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