ANSWER:-45 - 5 = -50

EXPLANATION:

When we subtract we move left down the number line and when we add we move right up the number line

..., -50 , -49, -48, -47, -46, -45 , ... , 0, 1, 2, 3, 4, 5, ...

We are at -45 on the number line

..., -50 , -49, -48, -47, -46, -45 , ... , 0, 1, 2, 3, 4, 5, ...

We want to subtract 5 so we move 5 numbers to the left

..., -50 , -49, -48, -47, -46, -45 , ... , 0, 1, 2, 3, 4, 5, ...

This puts us at -50 therefore -45 - 5 = -50

-4x + 7 = 2y - 3<br> y-intercept:<br><br> x intercept:
pantera1 [17]

Answer:

x-intercept: \bigg(\frac{5}{2}, \:0\bigg)

y-intercept: (0,\:5)

Step-by-step explanation:

To find the x-intercept, substitute in 0 for y and solve for x.

-4x + 7 = 2y - 3

-4x+7=2\left(\bold{0}\right)-3

Simplify 2(0):                                          -4x+7=2\cdot \:0-3

Subtract 0 - 3 = -3:                         -4x+7=-3

Subtract 7 from both sides:          -4x+7-7=-3-7

Simplify:                                         -4x=-10

Divide both sides by -4                \frac{-4x}{-4}=\frac{-10}{-4}

\bold{x=\frac{5}{2}}

To find the y-intercept, substitute in 0 for x and solve for y.

-4x + 7 = 2y - 3

-4(\bold{0})+7=2y-3

Switch sides:                               y-3=-4\left(0\right)+7

Simplify -4(0):                              2y-3=-0+7

Add 3 to both sides:                  2y-3+3=7+3

Simplify:                                      2y=10

Divide both sides by 2:             \frac{2y}{2}=\frac{10}{2}

\bold{y=5}
