Find the Equation with a Point and y-Intercept
(10,10)(10,10) , b=1b=1
Step 1
Find the value of mm using the formula for the equation of a line.
y=mx+by=mx+b
Step 2
Substitute the value of bb into the equation.
y=mx+1y=mx+1
Step 3
Substitute the value of xx into the equation.
y=m(10)+1y=m(10)+1
Step 4
Substitute the value of yy into the equation.
10=m(10)+110=m(10)+1
Step 5
Find the value of mm.

Step 5.1
Rewrite the equation as m(10)+1=10m(10)+1=10.
m(10)+1=10m(10)+1=10
Step 5.2
Move 1010 to the left of mm.
10m+1=1010m+1=10
Step 5.3
Move all terms not containing mm to the right side of the equation.

Step 5.3.1
Subtract 11 from both sides of the equation.
10m=10-110m=101
Step 5.3.2
Subtract 11 from 1010.
10m=910m=9
10m=910m=9
Step 5.4
Divide each term in 10m=910m=9 by 1010 and simplify.

Step 5.4.1
Divide each term in 10m=910m=9 by 1010.
10m10=91010m10=910
Step 5.4.2
Simplify the left side.

Step 5.4.2.1.1
Cancel the common factor.
10m10=910
Step 5.4.2.1.2
Divide m by 1.
m=910
m=910
m=910
m=910
m=910
Step 6
Now that the values of m (slope) and b (y-intercept) are known, substitute them into y=mx+b to find the equation of the line.
y=910x+1
