Question

The slope is 7, and it passes through ( 8, 6). a. y = 7x - 50 c. y = 7x + 6 b. y = 14x - 50 d. y = 7x + 62

Answer 1

Using slope-point form $y-y_1=m(x-x_1)$, we have $y-6=7(x-8)$. Converting this to slope-intercept form $y=mx+b$, we get $y=7x-50$.

Answer choice A.

Answer 2

Answer:

The equation of a straight line can be represented in the slope-intercept form, y = mx + c

Where c = intercept

Slope, m =change in value of y on the vertical axis / change in value of x on the horizontal axis

change in the value of y = y2 - y1

Change in value of x = x2 -x1

y2 = final value of y

y 1 = initial value of y

x2 = final value of x

x1 = initial value of x

The slope of the line is 7 and it passes through (8,6).

To determine the intercept, we would substitute x = 8, y = 6 and m= 7 into y = mx + c. It becomes

6 = 7 × 8 + c

c = 6 - 56 = - 50

The equation becomes

y = 7x - 50
