Answer:

y = 3/4x

Step-by-step explanation:

We need to find the slope of the line

We have point (0,0) and point (4,3)

m = (y2-y1)/(x2-x1)

= (3-0)/(4-0)

=3/4

The y intercept is 0 since it crosses the y axis at 0

The slope intercept form of the line is

y = mx+b

y = 3/4x +0

y = 3/4x

Write the equation of the line in fully simplified slope-intercept form.

Nastasia [14]

Answer:

y= $\frac{5}{6} x$ + 4

Step-by-step explanation:

Pick two points: (-6,-10) and (0,4)

Then solve for m (slope): I picked (0,4)

$m= \frac{4-(-1)}{0-(-6)} =\frac{5}{6}$

Then put in slope intercept form:

4= $\frac{5}{6} (0)$ + b

4=b

Then put in final form:

y= $\frac{5}{6} x$ + 4

Hope this helps!
