The slope-intercept form is y=mx+b, where m is the slope and b is the y-intercept.
y=mx+b
Reorder -32 and 5×2.
y=5×2-32
Rewrite in slope-intercept form.
y=52x-32
y=52x-32
Use the slope-intercept form to find the slope and y-intercept.
Tap for more steps…
Find the values of m and b using the form y=mx+b.
m=52
b=-32
The slope of the line is the value of m, and the y-intercept is the value of b.
