Please help I learned this a while ago and forgot how to do it

Answer:

The slope-intercept form is y=\frac{1}{2}x+\frac{11}{2}

Step-by-step explanation:

To find the slope, use

m=\frac{y^2-y^1}{x^2-x^1}

Replace the x and y values with the points.

m=\frac{7-5}{3-(-1)}

Solve.

m=\frac{2}{4}

m=\frac{1}{2}

After that, find the y-intercept form.

Put the equation in point-slope form.

y-5=\frac{1}{2}(x+1)

Replace x with 0.

y-5=\frac{1}{2}(0+1)

y-5=\frac{1}{2}

Add 5 to both sides.

y=5\frac{1}{2}

Convert to improper fraction form.

The y-intercept is \frac{11}{2}

Now finally, write in slope-intercept form. (y=mx+b)

m is slope, b is the y-intercept.
