Lets put the problem all together first
1) p^2+mn
2^2+0(-1)
Now we start
2x2=4
0x-1=0
4+0=4
Your answer should be 4:)
2) m+np^2
0+-1(2)^2
2x2=4
-1x4=-4
0+-4=-4
Your answer should be -4:)
2(3x) and 2(-9)
so 2*3x equals 6x and 2*-9 equals -18
6x-18

Answer:</h2>
First, we must determine the slope, then we find the y-intercept using slope formula and slope-intercept form.
<u>For slope:</u>
<u />
<u />
Slope (m) = 7
<u>For y-intercept:</u>
<u />
<u />
Y-intercept (b) = 26
Using this information, we can now create the equations for this line.

Formulas:
Slope formula: <em>y₂ - y₁/x₂ - x₁</em>
Slope-intercept form: <em>y = mx + b</em>
Point-slope form: <em>y - y₁ = m(x - x₁)</em>
<em></em>
*Note: (x₁, y₁), (x₂, y₂) = <em>2 points on the line</em>
Answer:
