# How do you graph  y = -3x + 4 ?

Jul 9, 2015

Determine two points on the line. Plot the points and draw a straight line through the points.

#### Explanation:

$y = - 3 x + 4$ is in the slope-intercept form for a linear equation: $y = m x + b$, where $m$ is the slope, and $b$ is the y-intercept.

Point 1:
If x=0;
$y = - 3 \cdot 0 + 4 = 0 + 4 = 4$

Point 1$=$$\left(0 , 4\right)$

Point 2:
x=2;
$y = - 3 \cdot 2 + 4 = - 6 + 4 = - 2$

Point 2:
$\left(2 , - 2\right)$
