Question

(-3,5) and (3,-9)

slope: -4

what is the point slope form ?

what is the slope intercept form ?

Answer 1

Point Slope Form: (y - 5) = -7/3(x + 3)
Slope Intercept Form: y = -7/3x - 2

The formula for point slope form is (y - y1) = m(x - x1) and the formula for slope intercept form is y = mx+ b. y1 is the y coordinate of an intercept and x1 is the x coordinate. m stands for slope in both equations, which you would find by (y2 - y1)/(x2 - x1). b in the slope intercept form is the point at which the line intersects with the y axis.

Answer 2

= -3+5+3-9

= -12+8

= -4

Explanation:

All the numbers with their sign are written in first step.

Then, the numbers having same sign are added in second step.

After that their calculation is done and the answer is -4.

Am I right...?
