Area is 35

Perimeter is 26

A = hb/2

Step-by-step explanation:

You're given the base (7) and the height (10). The area formula is .

The area of a triangle is half of the base times the height. 7 * 10 = 70, so 70 is twice the area. Divide it by 2 to get the area (35).

The perimeter is all of the sides added together. 10 + 8 + 7 = 26

y = 3x+4

step-by-step explanation:

to find the slope

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

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
