CPM Homework Help : CAAC Problem 7-90

7-90.

Hint:

Hint (a):

See the hint above.

Answer (a):

Slope = 3
y-intercept = (0,5)

Hint (b):

This equation is the same as:

$y=\frac{5}{-4}x+0.$

Answer (b):

$\text{Slope }=\frac{5}{-4}x$

y-intercept = (0,0)

Hint (c):

If there is no x-value in the equation, can there be a slope or is it 0?

Answer (c):

Slope = 0
y-intercept = (0,3)

Hint (d):

See part (a) and the first hint in the problem.

Hint (e):

Solve the equation for y. By doing this, you put the equation in y = mx + b form.

Hint (e):

Subtract by 3x on each side.

See this step (e):

4y = −3x − 4

Hint (e):

Divide by 4 on both sides.

See this step (e):

$y=\frac{-3}{4}x-1$

Hint (f):

See part (e) and the first hint in the problem.
