# How do you find the slope and y intercept for y=-7x+4?

Mar 11, 2018

slope = -7, y-intercept (0, 4)

#### Explanation:

$y = m x + b$
so m is the slope that is -7 in the equation $y = - 7 x + 4$

To find y-intercept, let x = 0

$y = - 7 \left(0\right) + 4 = 4$
(0, 4) is the y-intercept

$\text{slope "=-7," y-intercept } = 4$

#### Explanation:

$\text{the equation of a line in "color(blue)"slope-intercept form}$ is.

•color(white)(x)y=mx+b

$\text{where m is the slope and b the y-intercept}$

$y = - 7 x + 4 \text{ is in this form}$

$\text{with slope "=m=-7" and y-intercept } = b = 4$
