Answer:
its c
Step-by-step explanation:
Answer:
y = 4x + 7
Step-by-step explanation:
the equation for a line is y = mx+b
the y intercept is (0,7)
so in the equation x= 0 and y= 7 and the slope is m, thus m= 4
7= (4)(0)+b
now solve for b
7 = 0 +b
7= b
so the equation of the line would be without the x and y points
y = 4x + 7
Answer:
m(0.10)+15
Step-by-step explanation:
X is representing the miles driven. Then we're adding $15 for the rent fee.
The answer i think is it c
Answer:
Step-by-step explanation:
<u>The line with points (1,2) and (-1,-8). Work out its equation.</u>
<u>The slope is:</u>
- m = (-8 - 2)/(-1 - 1) = -10/-2 = 5
<u>To find the y intercept, substitute x and y-xoordinates of point (1,2):</u>
- 2 = 5(1) + b
- b = 2 - 5
- b = -3
<u>The line is:</u>
<u>Point (x, 17), substitute y-coordinate and solve for x</u>
- 17 = 5x - 3
- 5x = 17 + 3
- 5x = 20
- x = 20/5
- x = 4
