The slope-intercept form is y=mx+b, where m is the slope and b is the y-intercept.
y=mx+b
Reorder 203 and 2×3.
y=2×3+203
Rewrite in slope-intercept form.
y=23x+203
y=23x+203
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=23
b=203
The slope of the line is the value of m, and the y-intercept is the value of b.
Slope: 23
y-intercept: 203
Slope: 23
y-intercept: 203
Any line can be graphed using two points. Select two x values, and plug them into the equation to find the corresponding y values.
