Answer:
Slope = , X-intercept = 8 , Y-intercept = -4
Step-by-step explanation:
the following equation is given in slope intercept form which is y = mx + b where m is the slope and b is the y intercept
since m = and b = -4, we can say our slope is
and y intercept is -4.
Recall that x intercept occurs when y = 0 so plug y = 0 in the equation then solve for x
0 = x - 4
add 4 to both sides,
4 = x
multiply by 2 on both sides,
4*2 = x
8 = x
x = 8
so our x-intercept is 8
Answer:
The answer is
<h2>y = - 8x + 8</h2>Step-by-step explanation:
To find the equation of the line given a point and slope we use the formula
where
m is the slope
( x1 , y1) is the point
From the question the point is
(1/2,4) and slope m = -8
The equation of the line is
We have the final answer as
<h3>y = - 8x + 8</h3>Hope this helps you
