What is the slope of the line passing through the points. ( -1, 3 ) and ( 4, -7 )
On a coordinate plane.

-6 is the slope

Step-by-step explanation:

In order to find the slope you need to do put it in slope intercept form

y2-y1/x2-x1 is slope-intercept  form

(-7 - (-1))/4-3 = (-7 +1)/1 = -6/1 = -6

The slope in -2

Step-by-step explanation:

to graph this use the slope-intercept form of y=-2x+1

area of trapezoid= 1/2 × ( a + b ) × high

75cm² = 1/2 × (8+17) × h

75. = 1/2 × 25 × h

75. = 12,5 × h

75. = 12,5h

h = 75 ÷ 12,5

h. = 6 ( B )
