Im failing 15 points will mark asap

points (-3,0) (0,4)

slope = (y2-y1)/(x2-x1)

m=(4-0)/(0--3)

m=4/3

point slope form

y-y1 = m(x-x1)

y-0 = 4/3 (x--3)

y = 4/3 (x+3)

y = 4/3 x +4

slope intercept form

The slope-intercept form:

m - slope

b - y-intercept → (0, b).

Let's take two point of the graph (look at the picture)

(-3, 0) and (0, 4) ← y-intercept, therefore b = 4

The formula of a slope:

Substitute:

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.
