For each line below, name the slope and y-intercept. Homework Help ✎
3x + y = −7
y = + 8
y = −2
This equation, rewritten, is the same as saying:
Knowing this information, can you identify the y-intercept and the slope?
Rewrite the equation in y = mx + b form, then identify the slope and the y-intercept.
The equation is already in y = mx + b form, so identify the slope and y-intercept in the equation.
Remember that y = −2 is a horizontal line.
Because it is horizontal, the line has zero slope and the y-intercept is given right in the equation, −2.
