What is the equation of a line with a x-intercept of −2 and a y-intercept of 10?
IceJOKER [234]

Hey there! :)

Answer:

y = 5x + 10

Step-by-step explanation:

From the information given, we can derive the points (-2, 0) and (0, 10). Find the slope using the slope formula:

m = \frac{\text{rise}}{\text{run}} = \frac{y_2 - y_1}{x_2 - x_1}

Plug in the points:

m= \frac{10 - 0}{0 - (-2)}

Simplify:

m= \frac{10}{2}

m = 5.

The equation in slope-intercept form is y = mx + b. We were already given the b value, or y-intercept as y = 10. Therefore:

y = 5x + 10 is the equation written in slope-intercept form.

4/3 x+12=-4 hell please right answer get brainliest points and show work please
IrinaVladis [17]

Answer:

x = -12

Step-by-step explanation:

4/3x + 12 = - 4   (multiply 3 both side)

4x + 36 = - 12 (minus 36 both side)

4x + 0 = -12

4x = -12 - 36

4x = - 48 (divide both side)

4x ÷ 4 = x

-48 ÷ 4 = -12

Answer: x = -12
