Answer:
y=3x+5
Step-by-step explanation:
Slope is rise/run. To find it, you first see how many units it goes up, followed by how many units it goes to the right. If you look at the point (-1, 2), it rises 3 tiles, and runs 1 tile until it hits the next whole number. Because your little formula is rise/run, it would be 3/1, or 3. And to get your y-intercept, it's just when it intersects the y-axis, which is at 5. So, your equation would be y=3x+5
Answer:
The answer is 27 If not please correct me!
Answer:
Step-by-step explanation:
The slope-intercept form of an equation of a line:
m - slope
b - y-intercept
We have the slope 
and the point (-2, 4).
Put them in the equation of a line:
<em>add 4/5 to both sides</em>
