Answer:
y=-1/2x-3 = slope-intercept
y+5=-1/2(x-4) = point-slope
Step-by-step explanation:
I used the slope and the point provided to get other points and eventually the y-intercept to complete the slope-intercept equation.
I plugged in the numbers provided to get the point-slope equation.
Answer: Please, see the attached file.
Thanks.
Solution:
We can graph using the intercepts:
(1) y-intercept, when x=0
y=4x-3→y=4(0)-3→y=0-3→y=-3
Point=(x,y)=(0,-3)
(2) x-intercept, when y=0
y=4x-3→0=4x-3
Solving for x: Adding 3 both sides of the equation:
0+3=4x-3+3
3=4x
Dividing both sides of the equation by 4:
3/4=4x/4
3/4=x
x=3/4=0.75
Point=(x,y)=(3/4,0)=(0.75,0)
With these pair of points (0, -3) and (0.75,0) we can draw the right line
